Title: Devices for feeding closures to closing machines of rotary construction handling crown corks or similar closures
IPC: B67B3/10
Filed: 1970-08-04
Abstract: 1320007 Feeding bottle caps; capping bottles SEITZ-WERKE GmbH 4 Aug 1970 [4 Aug 1969] 37493/70 Headings B8A, B8T and B8S The invention relates to a device for feeding closures 13 to vessel closing machines which have multiple closing heads 10 arranged on a circular track, the device sequentially moving closures (standing in readiness at the delivery end of a slide track 23 arranged between the vessel inlet 11 and outlet 12 of the closing machine) into empty pockets in the closing heads which are placed to one side of and below a closing member and open to the slide track. A moveable probe 29 is associated with each closing head for testing the pocket in the head during circulation of the closing head in the region between the vessel outlet 12 and the end of the slide track 23 for the presence of an included closure. A carrier 26 is controlled by movement of the probe 29 and which, in each case, where the pocket is unoccupied (Fig. 3) removes a foremost closure from the slide track end to move the closure with the aid of a guide 41 to the empty pocket. A closure stop 35 common to the closure heads, situated along the circulation track between the vessel outlet of the machine and the slide track end and opposite to the probe, causes the adjustment of the probe in the presence of an included closure (Fig. 2). Thus in Fig. 3 where an approaching pocket is unoccupied, the carrier 26 is projected and engages behind and carries round the leading closure waiting in the track 23. In Fig. 2 where the approaching pocket is occupied, due to engagement of the probe 29 by the closure, (and reaction of the latter against a confining flange 27) the probe 29 is displaced (rightwards as seen in Fig. 2) thereby to retract the carrier 26. The leading closure in the track 23 thus remains stationary on a plate 40 forming the base of the track. As shown, the transmission between the probe 29 and the carrier 26 is effected by a flexible cable 37. In a modification (Fig. 6, not shown) the probe 29 is integral with a fluid valve element which controls the application of fluid pressure used to actuate the carrier 26. In another modification an arrangement (Figs. 9, 10, not shown) of pivoted links is used to effect the transmission. The function of the stop 35 is to progressively move the stop mechanism into a position where the probe is able to protrude into the pocket. In another arrangement, (Fig. 11, not shown), the stop 35 is replaced by a modification of the flange 27 which is shaped so as to progressively drive the closure more deeply into the pocket.

Abstract: 1,163,056. Lens mountings. FRANKIE & HEIDECKE G. m. b. H. [trading as ROLLEI-WERKE FRANKIE & HEIDECKE]. Aug. 15, 1967 [Sept. 14, 1966], No. 37512/67. Heading G2A. The objective carrier 1 of a single lens reflex camera has extended side arms 2 which are slotted as at 3. Guide blocks 4 engage within the slots 3, so that the carrier 1 is guided for sliding movement along the optical axis by the guides 4. These guide blocks themselves are pivotable on a shaft 5 transverse to the optical axis, and placed as close as possible to the film plane. The pivoting movement of guides 4, and hence carrier 1, may be effected externally by a shaft 8 and pinion 7, which engages with a toothed segment fixed to the guide 4. The side arms 2 carry a rack member 9, the rack part being engageable by eccentric ribs 10 on a disc rotated by a shaft 12. Thus the racks 9, and hence the side arms 2 and the objective carrier, can be moved axially in a focusing movement.

Title: Crystal growing method
IPC: C30B7/00
Filed: 1954-12-29
Abstract: <PICT:0761848/III/1> <PICT:0761848/III/2> <PICT:0761848/III/3> A method of growing a crystal comprises exposing a crystal seed to an aqueous solution of the crystal salt, causing the solution to crystallize on the seed, and restraining crystal growth in the direction of the Z crystallographic axis.  The crystal may be a P-type, crystal, particularly primary ammonium phosphate.  A crystal seed of primary ammonium phosphate in the form of a rectangular bar 10 (Fig. 1) elongated in the direction of the Z axis and having side faces perpendicular to the x and y axes, is placed in a groove 11 formed in a tray 13 with baffle plates 16 and 17 which abut against opposite ends of the crystal seed 10. The tray is immersed in an aqueous solution of primary ammonium phosphate in a tank which is rocked so that the solution flows back and forth across the crystal seed as the temperature is lowered gradually, causing a crystal 18 to grow, the baffles 16 and 17 preventing crystal growth in the direction of the Z axis. A horizontal baffle may be provided above the crystal seed and between the end baffles to prevent vertical growth beyond a desired amount.  In another arrangement (see Fig. 4) a crystal seed 27 elongated in the direction of the Z axis but with side faces 28 to 31 cut at 45 degrees to the x and y axes, is placed in a groove in a tray 21 as shown, with its ends abutting against vertical baffles as before, and a crystal grown, the seed first growing a triangular prism 32 having side faces at right angles to the x and y axes, growth then proceeding as in Fig. 1.  In a modification a crystal seed as in Fig. 4 is cemented to a flat upper face of a tray between end baffles, and a crystal grown, the seed first growing side faces perpendicular to the x and y axes. In a further embodiment (see Fig. 7) a crystal seed 55 elongated in the direction of the Z axis and having side faces perpendicular to the x and y axes, is received in V-shaped notches 53 and 54 in walls 51 and 52, with its lower end on a tray 50 and its upper end against a horizontal baffle 58.  A crystal is grown in a rocking tank as before, growth outwardly from the seed being limited by baffles 56 and 57, the fully grown crystal having prism faces 64, 65, 66 and 67. In a modification a crystal seed 75 (Fig. 7) having side faces at 45 degrees to the x and y axes is received in notches 73 and 74 in walls 71 and 72.  The seed first grows side faces at right angles to the x and y axes and then grows outwardly as before, being limited by baffles 57 and 70.  The solution for growing primary ammonium phosphate crystals contains no more than 30 parts of ferric iron and 0.1 parts of trivalent chromium per million parts of salt, to avoid inhibition of crystal growth perpendicular to the Z axis.

Title: Improvements relating to the production of thiocarbamides and derivatives of glyoxaline
IPC: C07D233/64
Filed: 1930-12-20
Abstract: 1-Substituted glyoxalines are prepared by condensing acetalylthiocarbimide with an amine and converting the resulting thiocarbamide into the glyoxaline derivative in known manner.  The amines employed are of the aliphatic, aromatic, or heterocyclic series, and give rise to glyoxalines containing an aliphatic, aromatic, or heterocyclic residue in position 1.  Examples are given of the preparation of (1) 1-(quinolyl-8)-glyoxaline by heating 8-aminoquinoline with acetalylthiocarbimide, treating the 8-acetalylquinolylthiocarbamide with dilute sulphuric acid on the water bath to close the glyoxaline ring and form 1-(quinolyl-8)-2-thiolglyoxaline, and the mercapto group then eliminated by treatment with nitric acid; in the same way, 2-aminoquinoline is converted into 1-(quinolyl-2)-glyoxaline via 2-quinolylacetalylthiocarbamide and 1-(quinolyl-2)-2-thiolglyoxaline, and 6-methoxy-8-aminoquinoline is converted into 1-(6-methoxyquinolyl-8)-glyoxaline through the thiocarbamide and thiolglyoxaline stages; (2) 1-b -hydroxyethyl)-glyoxaline by interaction of b -aminoethyl alcohol with acetalylthiocarbimide, closing the glyoxaline ring by heating with dilute sulphuric acid, and oxidizing the resulting 1-(b -hydroxyethyl)-2-thiolglyoxaline with nitric acid; in the same way, glyoxaline-1-acetic acid is prepared from aminoacetic acid ethyl ester.  An example is also given of the conversion of acetalylthiocarbimide into phenylacetalylthiocarbamide by heating with aniline.  The Provisional Specification states that acetals containing other groups than the ethyl group may be employed.  Acetalylthiocarbimide is obtained by heating aminoacetal with carbon disulphide in the presence of a desulphurizing agent.  An example is given of the use of basic lead acetate.

Filed: 1969-10-27
Abstract: 1,207,698. Thermonuclear fusion. A. P. PEDRICK. 27 Oct., 1969, No. 38562/68. Heading G6P. [Also in Divisions H1 and H2] An arrangement for generating electrical power from a plasma comprises a spherical shell 8 at the centre of which there is supported a ball 10 of plasma-forming material, a plurality of lasers 4 being directed on to the ball and being simultaneously pulsed to create a plasma, the plasma so formed being subjected to the e.m. field of a coil 13 to constrict and modulate it as it flows upwards, and the modulated plasma generating an alternating current in a coil 14, this current being supplied to a transformer whose output may feed an electrical grid. As shown, the balls 10, which may be of deuterium or deuterium and tritium, are carried to the centre of the sphere 8 by an inert gas flowing through tube 11. Water and air-cooling systems are also shown. The Specification describes ways in which the laser beams may be focused on the ball (Figs. 1, 2 and 5, not shown), and the method whereby the lasers are triggered at the instant when the ball is in the centre of the sphere (Fig. 6, not shown). The Specification also describes so called " laser beam compression guns " for producing the pulses of laser energy. Fig. 7 shows an example of such an arrangement wherein laser energy is fed into the end of a tube 71 through a hole in a bullet 76, and is reflected at a diaphragm 73. When the bullet, which has a reflecting front end, is fired it travels up the tube compressing the energy until this bursts through the diaphragm to be focused by a lens 79 on the target ball 70. Several more elaborate examples are disclosed (Figs. 8-15, not shown).

Abstract: 1,114,749. Valves. D. G. GRISWOLD. 9 Sept., 1965 [1 Oct., 1964], No. 38569/65. Heading F2V. An in-line valve for aircraft tank fuel filling has a valve member 64 with outer and inner skirts 66, 68 slidable on a fixed piston 32 with corresponding outer and inner piston parts 58, 56. The outer skirt 66 co-operates with a preferably resilient seat 18 at the inlet end of the valve body 2. A chamber 74 enclosed between the inner piston part and the valve member is open to atmosphere through a passage 48. Pressure in the outer chamber 72 of the valve member is equalized with the downstream pressure through openings 84. The valve is thus responsive to outlet pressure on an area corresponding to piston part 56 to closed position and is biased to open position by a spring 76. Instead of atmospheric pressure, a control pressure may be applied to the chamber 74. In the event that high pressure is trapped in the outlet by the closing of an adjacent manual nozzle valve (110), Fig. 6 (not shown), a ball valve 98 falls away from a seat 96 and pressures are equalized to allow the valve to re-open.

Conductors arranged in two or more side-byside stacks in a slot change their positions in the same stack or pass from one stack to another and have bent portions at least at the top and bottom of a stack arranged in such manner as to space the stacks apart, thereby providing coolant passages. In Fig. 1, each individual conductor lying at the top of stack 1 or stack 2 for part of the slot length passes to the bottom of the same stack for another part of the slot length by means of bent parts 3, 4 which rest against the stack sides and determine the slot widths. Instead of the right-angle bends the transversely extending portions at the top and bottom of the stacks can be connected by indined members 14, 15, the width of which is such as to leave passage for coolant. Instead of the inclined members crossing, they could all be in parallel. In Fig. 4, each top and each bottom conductor passes from one stack in the other while additional spacers are provided in the form of some bars such as 25 at intermediate level being bent out to touch the other stack before returning to its own. Where the conductors all stay in the same stack a central insulator radially disposed can bisect the ducts between two stacks. Hydrogen or liquid may be passed axially along the ducts between the stacks.

Abstract: 843,949. Friction clutches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 28, 1956 [Dec. 30, 1955], No. 39528/56. Class 80 (2). [Also in Groups XXXV and XXXVI] An electrostatically engaged friction clutch comprises a clutch member made from a semiconducting material, a second clutch member made from a conducting material, and means for applying an electrical potential difference between the two members so as to clutch them together, lubricant being disposed between the two members. A pulley 13 can rotate on a shaft 11 and carries by insulating means 17, &c. a metal ring 15 over which slides a brush 19. Fast with the shaft 11 is a brass &c. hub 12 carrying a ring of semi-conducting material 24. A band 26 of, e.g. stainless steel is secured at one end 27 to the ring 15 and at its other end is connected to a spring 28 also secured to the ring, the arrangement being such that the spring engages the band lightly with the outer surface 25 of the semi-conducting ring. A block of lubricating material 29, which may be tetrafluorethylene resin, is held in the ring 15 and biased against the outer surface 25 of the semiconducting ring 24 by a spring 31. A mohair or like brush 32 is carried by the ring 15 to wipe the surface 25. Either the shaft 11 or the pulley 13 may be the driving member of the clutch. When a switch 23 is open, the outer surface 25 of the semi-conducting ring 24 and the band 26 are free to slide over one another. When the switch 23 is closed, the potential of a battery 22 is applied through the brush 19 to the ring 15 and the band 26, and also through a brush 21 to the conducting hub 12 fast with the shaft 11. The band 26 is thus attracted to engage the outer surface 25 of the semi-conducting ring 24 for the transmission of torque. The material from which the semi-conducting ring 24 is made may include natural or synthetic rubber, phenolic, asbestos and carbon. One material which may be employed comprises the following ingredients in proportions by weight of: 162 parts rubber, 200 parts phenolic resin, 240 parts asbestos, 6 parts zinc oxide, 6 parts sulphur, 3 parts stearic acid, 3 parts zinc stearate, 3 parts antioxidant, 1.5 parts mercaptobenzothiazole, 0.3 parts zinc dimethyldithiocarbamat and 166 parts carbon black.
